It should be Stock Service Pistol Division (SSP). But it all depends on the internal workings if the striker is cocked and released or just released. I believe the M&P is a cocking action striker gun. If the striker is just released than it falls into the Enhanced Service Pistol Division (ESP). M&P guns where not out when I shot IDPA, Now I shoot USPSA and the M&P is a Production Class gun. IMO IDPA has way too complex in its rules and procedures to be a fun sport.

1911s are the only pistol who get their own class which is CDP. It's kind of a double edges sword too. You all have the same pistol and caliber so it's equal, you aren't shooting a big caliber with heavier recoil and going against someone with say a 9mm tha tis light recoiling. But that is only an issue if you are not use to the recoil.

At the same time though at the club where I shoot someo f the best shooters are in CDP so for me as a new guy to IDPA it's a severe disadvantage. I get my *** kicked even when I do good. But I don't really care anyway. It's fun and decent practice.
